My present inventionf'relates to belt hooks ofthe type in'which aplurality of shanks and tangsare used for fastening and holdingtheilendsof "a belt together and the present improvement-has for itsvarious objects:

To provide "a compacucheap and very effiare simultaneously forced intothe endof the belt by providingmeans that .connectthe hooksv to, holdthem properly in spaced relation to] ne another while the connecting}means simultaneously lines up the hookswith. g

In the several figures ofjthe drawing like 5 reference.numerals'indicatelike parts. The belt hook' forming the subject matterofmypresentinvention'is used for the purpose of'fastening or lacingtogether the ends of a transmission belt in a manner that Will make thejoint strong, durable, and-What ,is mostimportant, safe to the man Whois workingrnear the moving belt'and is liable to come in contact withit. The belt hook isg made up of a pluralityof hook members-that arefirmly held togetherso that none of the and proje'ctfijom the beltandeither fiy ofi or cau'sea click or knock every time the hook passesover the pulley. fEmbedding the-hook members will alsoprevent defacingthe sillv faceofthe pulley; Furthermore the belt thebelt ends 7 and thebelt hooks, c the section made up of individual hook members that are 3firmly heldtogether by a connecting linkthe belt hook can" be applied tothe belt without js5 the aid of'anyspecial apparatus and only a hammerisneeded-to attach the belt hook to the belt ends. The elimination ofspecial ap- -paratusalsogives an unobstructed view of V the belt endmaking possible a perfect-ali'gli- E mentofthe belt'hook onthe belt end.

The individual hook members aswell as 1 the 'connecting link arepreferably made up iw of round Wire stock and because they are'tmadeofstock"in Which the cross sectional die ameter decreasestowardtheside that is? members will-read-ily-embed themselves intothejsurfacewof thebeltwhen pressur'e'is apthe hook members are firmlyheld together by a link or links so that all of the hooks are jointlylined up and applied together to the end of the belt. One blow from ahammer will therefore partially close all or a part of the hook membersand bring them in engagement with the belt in proper alignment and holdthem anchored thereto so that the individua-lihook members can then behamshort sides of the V shaped hook bodies are connectin g belt, but addto this the advantages of united hooks which stay united at alltimes,cannot fall apart, can be lined up on the end of a belt ass unitand be driven in place as a unit with a hammer.

As illustrated in the several figures of the drawing the improved belthook comprises a series of individual hook bodies 1, which are fastenedtogether by the connecting links or bars 3 and 4.; hen properly bent upeach of the hook bodies 1 consists of a practically V-shaped wire havinga rounded apex and with one side-of the V longer than the "other. Theouter ends of both the long and bent inwardly and are sharpened to formtangs 5 and 6 thereon.

, As illustrated in the figures of the drawing 1 the hook'members areplaced'in spaced relation'to each other and side by side with the longand short sides of these members alternating so that a long hook and itstang on "one side'confronts a short hook and its tang on the a otherside, the belt hooks are therefore driven into the bolt the tang on theshort side will be offset from the tang on the long side of each hookmember. In this way the engagement of the tangs with the belt will notinterfere with each other as they will engage at differentv points inthe belt so that the grip of the belt hook will be strong and .cannotloosen or tear out ofthe belt either partially or wholly. The tangs onboth the short and long sides.

of the hook are preferably ofthe. same length and penetrate the belt tothe same depth. T r

-with'relation to the edge atthe ends of the y ca belt; Theselinks orbars provide two parallel shoulders on the inside of the hook lVhen thetangs of v links or bars 3 and 4 also serve as a gage for lining up thebelt hook against which the edge of the end of the belt is placed beforeit is closed to force the tangs into the belt in the manner abovedescribed and illustrated in the drawing.

hen a belt hook has been applied to each of the free ends of the belt aseries of closed loops areformed at each end of the belt in staggeredrelation to each other. The loops of onebelt heck are then brought inengagement between the loops of the other belt hook to bring them inline with one another and allow the connecting pin to pass thru them andform the pivot of the joint between the two belt hooks and the ends ofthe belt to which they are fastened.

In Figure 4 I have shown that it is not necessary to use two connectinglinksor bars for holding the individual hooks in spaced rela tion to oneanother. One such connecting link is sulficient to hold them together.If but one such link is used it is possible to' place the'b'elt endbeyond this bar instead of against it. The belt hook then engages alarger portion of the end. ofthe belt and brings the joint between theends of the beltcloser together.

The fact that the connecting bar is made of round wire stock will allowthis member to embed itself into the surface of the belt with f theremainder of the hook members.

'Asillustr'ated in the figures of the draw-- ings theconnectingbarsaresimply welded to the. inside of the hookjmem'bers and this has beenfound to be very practical when done by electric welding. The individualpartsforming' the belt hook are placed. in a suitable jig where they areheld in proper relation to each other so that when the current isapplied all of the hook members are simultaneously welded together.

1. A belt hook comprising a series of hook members made up of materialhaving a cross section adapted to wedge itself into the surface of thebelt when pressure" is applied' to the outside thereof, a straightconnecting bar welded to said hook members to hold said hook members infixed spaced relation to one another and extending directly form onehook member to the other to form an integral shoulder and connecting.member on the inside of said'hook'members the full length of the belthook. i

2. A belt hook comprising a series of hook members made up in the formof a V and having a longand short side, a tang formed at the end of eachof the short and long sides of said V shaped hook members adapted toengage the upper and lower surface of a belt in olfset relation to eachother, a connecting bar Welded .to said hook members to form an integralpart therewith and connect said hook members side by side in fixedspaced relation with each other.
